Overview

AI-generated overview

Remote MCP endpoint that lets an assistant compute cryptographic hashes (MD5, SHA1, SHA256, SHA512, bcrypt) from text, paid per call via x402.

What you can do
  • Generate a cryptographic hash from supplied text using MD5, SHA1, SHA256, SHA512 or bcrypt, with SHA256 as the default.
  • Return the resulting hash string, the algorithm used and the hash length.
  • Settle each call through an x402 micropayment challenge rather than an API key.
When to use it
Useful when an assistant needs a quick hash of a short piece of text and you are willing to pay a few tenths of a cent per call in USDC. For routine local hashing, a local tool is usually simpler and free.
Requirements
Remote SSE endpoint at hash-generator.api.klymax402.com; no package, API key or signup. An x402-capable client with a funded wallet holding USDC on Base L2 (eip155:8453) is needed to settle the per-call charge; the README lists $0.003 per hash call.
Before you install
Every call costs money: the endpoint answers with a 402 payment challenge and an x402 client signs and retries, spending USDC from your wallet on Base. No API key is used, so the wallet is the credential. Text you submit is sent to a third-party service, so avoid hashing secrets or sensitive data.

Installation

In SourceWeft

  1. Open Hash Generator API in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via SSE. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.Br0ski777%2Fhash-generator/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

README

Hash Generator API

[MCP Server] [x402] [License: MIT]

Cryptographic hash generator supporting MD5, SHA1, SHA256, SHA512, and bcrypt. Pay-per-call via x402 (USDC on Base L2) -- no API key, no signup, no rate-limit wall.

Part of the klymax402 marketplace -- 100 x402 micropayment APIs for AI agents, one wallet, USDC on Base.

Quickstart -- MCP

Add to your MCP client config (Claude Desktop, Cursor, ElizaOS, etc.):

json
{  "mcpServers": {    "hash-generator": {      "url": "https://hash-generator.api.klymax402.com/mcp"    }  }}

Quickstart -- HTTP (x402)

bash
curl -X POST "https://hash-generator.api.klymax402.com/api/hash" \  -H "Content-Type: application/json" \  -d '{"text":"..."}'# -> 402 Payment Required, with an x402 payment challenge in the response body

Any x402-aware client (@x402/fetch, x402-agent-tools, ATXP) handles the 402 -> sign -> retry cycle automatically.

crypto_generate_hash

Use this when you need to generate a cryptographic hash of text. Supports md5, sha1, sha256, sha512, and bcrypt algorithms. Returns the hash string, algorithm used, and hash length. Do NOT use for password strength checking — use security_check_password. Do NOT use for data validation — use data_validate_json.

Score

50% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 daysRequired25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declaredRequired10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.

  • Tools listed15 pts

    Answer tools/list without a credential, or ship a package that starts in a sandbox without one.
